Abstract:
A method may include generating a signal at an initiating device. A channel in an optical path may be identified, with the optical path including at least two spans. Simulated polarization mode dispersion (PMD) is injected into the signal to generate a test signal. The test signal is transmitted on the channel and received at a destination device. PMD effects in the test signal are compensated, and a measurement of PMD for the test signal is determined based on the compensation, the PMD for the test signal including PMD for the channel and the injected PMD. A measurement of the PMD for the channel is determined based on the PMD for the test signal and the injected PMD.
